Recent Progress on the Ls-stag Immersed Boundary Method for the Computation of Viscoelastic and Pseudo-plastic Liquids

چکیده
This communication presents a progress report on an ongoing project aiming at the computation of complex fluid flows with a realistic constitutive law, which would takes into account the pseudoplastic, viscoelastic and thixotropic behaviour of the materials. The flow solver is based on the LS-STAG method, which is an immersed boundary (IB) method that allows the computation of flows in complex geometries on simple Cartesian meshes, reducing thus the bookkeeping of body-fitted methods. One of the distinguished features of our method is to use level-set (LS) techniques for sharply representing the irregular boundary. The LS-STAG method has been validated on canonical Newtonian flows in both fixed and moving geometries [1].

A Fast Immersed Boundary Fourier Pseudo-spectral Method for Simulation of the Incompressible Flows
Abstract The present paper is devoted to implementation of the immersed boundary technique into the Fourier pseudo-spectral solution of the vorticity-velocity formulation of the two-dimensional incompressible Navier-Stokes equations. The immersed boundary conditions are implemented via direct modification of the convection and diffusion terms, and therefore, in contrast to some other similar ...
متن کاملThe LS-STAG Method : A new Immersed Boundary / Level-Set Method for the Computation of Incompressible Viscous Flows in Complex Geometries
Much attention has recently been devoted to the extension of Cartesian grid flow solvers to complex geometries by immersed boundary (IB) methods (see [4, 6] for recent reviews). In these methods, the irregular boundary is not aligned with the computational grid, and the treatment of the cells which are cut by the boundary remains an important issue. Indeed, the discretization in these cut-cells...
متن کاملViscoelastic Immersed Boundary Methods for Zero Reynolds Number Flow
The immersed boundary method has been extensively used to simulate the motion of elastic structures immersed in a viscous fluid. For some applications, such as modeling biological materials, capturing internal boundary viscosity is important. We present numerical methods for simulating Kelvin-Voigt and standard linear viscoelastic structures immersed in zero Reynolds number flow. We find that t...

In this paper, a mathematical model for symmetrical multi-layer sheet rolling, in which the layers are unbounded before rolling, by using the upper bound method and stream function theorem is proposed. Using this model, we can investigate the plastic deformation behavior of sheets at the roll gap during rolling. Effect of various rolling conditions such as initial and final thickness and flow s...
